2011 Wireless System Questions

[HarryScheiner]

We've been having a hell of a time trying to get the wireless to work with our robot. We are using Java with Netbeans. I am really not sure what the problem is so I'm just going to start listing things we have done and hopefully someone can tell us something we've missed.

Things we have done:

1. Set up the DAP-1522 by following this
   
2. Connected our ClassMate, Driver Station, DAP-1522, and cRIO like so:
   
   
   ClassMate <--ethernet--> Driver Station <--ethernet--> DAP-1522 <--ethernet--> cRIO
   
   Using this tethered connection, we can load new code onto the robot and control it just fine.
   
3. Attempted to connect our ClassMate, Driver Station, DAP-1522, and cRIO like this:
   
   
   Driver Station <--ethernet--> ClassMate <--wifi--> DAP-1522 <--ethernet--> cRIO
   
   with no luck. The ClassMate connects to the DAP-1522, but the Driver Station says "No Comm".

Other things we have tried might be slipping my mind right now, as I am at home. One thing that I am NOT sure of is that we are using the correct Driver Station. Is the Driver Station this object, or is it the Driver account on the ClassMate?

Are you in an area with lots of Wifi usage? We have been having issues with testing our robot over wireless when we are in areas of moderate to high 2.4ghz Wifi usage, such as the student center at NU.

There are a couple different access points, but we were on campus in the evening when hardly anyone is around. I don't think there was a lot of wireless activity going on. The connection said it was pretty strong. Which Driver Station are you using? (I am really paranoid about this being the problem and just want to make sure it isn't overlooked )

You should be using the driver's station account on the Classmate. The blue box driver's station was only used for 2009 and should not be used for your setup this year.

The Driver Station is the Classmate. Do not use the blue box. It was the Driver Station in 2009 only.

Your Classmate (suitably updated, logged in as Driver, and running the Driver Station application) will connect wirelessly to your DAP (properly configured in Access Point mode) on the robot.

Excellent. It just dawned on me this morning that that was probably the issue, thank you for confirming it! I will report back later on if I get it working.

Okay, it still doesn't work. Can anyone walk me through exactly how this is supposed to be set up? Or point me to all the proper documents?

This is the current setup:

ClassMate <--ethernet--> LinkSys Router
and
DAP-1522 <--ethernet--> cRIO

I tried connecting the ClassMate to the DAP-1522 via wifi and got "limited connectivity". I read that this could mean that it just doesn't have internet access, which makes sense, but the driver account still says there is no connection.
On the driver account, we have:

• Enet Link
• DS Radio
• Bridge
• Robot
• FMS

EDIT: Fixed. I had to fix the settings in my wireless adapter on the ClassMate and remove the LinkSys router entirely. Thanks everyone!
